Transgender is the state of one's gender identity or gender expression not matching one's assigned sex. Transgender is independent of sexual orientation; transgender people may identify as heterosexual, homosexual, bisexual, etc; some may consider conventional sexual orientation labels inadequate or inapplicable to them. The definition of transgender includes:

"Of, relating to, or designating a person whose identity does not conform unambiguously to conventional notions of male or female gender roles, but combines or moves between these."

"People who were assigned a sex, usually at birth and based on their genitals, but who feel that this is a false or incomplete description of themselves."

"Non-identification with, or non-presentation as, the sex (and assumed gender) one was assigned at birth."

The Transition House Association of Nova Scotia (abbreviated THANS and TRANS) is a Halifax, Nova Scotia, Canada-based organisation that runs women's shelters. Pamela Harrison is THANS's executive director, and also serves as provincial co-ordinator. Rhonda Fraser, the executive director of Chrysalis House, is a member of THANS. THANS organises an annual purple ribbon awareness campaign in memory of the École Polytechnique massacre. THANS was founded in 1989. THANS conducted interviews with 34 physically abused women who subsequently sought resolution through family law mediation. In 2000, THANS released a report based on these interviews, stating that most of the women would not recommend legal mediation to other abused women. In 2008, THANS supported Bill 81, which they hoped would become the Domestic Violence Elimination Act, but Minister of Justice Cecil Clarke chose not to call the bill for a third reading. In 2009, Darrell Dexter of the New Democratic Party identified THANS in his promise to increase government funding of halfway houses in Nova Scotia. In 2012, THANS partnered with the World YWCA, Family SOS, Silent Witness Nova Scotia, and Leave Out Violence to host the Atlantic Ballet Theatre of Canada's Ghosts of Violence, a ballet about domestic violence, in Halifax.
